where do I claim 1099-S

LaLa

My family had had property for about 100 years and the responsibility has been split between 11 families. as the generations pass away the responsibility falls to the next generation. it was originally willed to my grandmother who passed away in 1993 and my mother who passed away in 1991. the property finally sold and each family got 35k but I had to be the executor of my grandmother's estate. and the payment was made to the estate of. how do I file the proceeds on the 1099S
